"When people involved with the show are looking at the long-term plan... they want something different - and what those differences are, you'd have to ask AMC," the writer/producer said.

Mazzara insisted that he is still grateful to have worked on The Walking Dead, despite the circumstances of his departure, according to Deadline.

"I was a hired gun coming in to support the creator of the show and, through odd circumstances, I ended up becoming the showrunner," he explained. "I was just glad that I was able to contribute and not mess up the show, I see that as a win."
